The RSH-TMR Remote Strobe & Horn comes with a mounting enclosure and combines two alarm features, a visual and an audible, into one compact device. The strobe and siren can be configured to activate together or each can activate separately from each other. It includes a built in timer that can be set for a predetermined amount of time, that when a gas reading level triggers the strobe/horn a press of the shut off switch will silence the alarm for that amount of time. The timer / shut off switch can be made to silence the horn, turn off the strobe or control both at the same time by changing jumper positions. It is powered by 24 VDC/VAC. May be used for light industrial, commercial and institutional applications for timing, paging and alarm signaling, including equipment malfunction alerts, safety and security warnings. Ideal for refrigeration applications to meet B52 code requirements.
